To all w7zom it may 'con cern:

Be 1t known that I, ABRAHAM M. ZIMMl-Ik- MAN, a resident of New Holland, in the county of Lancaster and State of Pennsylrepresents the engine fly wheel.

Vania, have invented certain new and useful Improvements in Means for Forcing (ooling Liquid to Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will onable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for circulatmg fluuls through the cooling nicaifs of engines,the object of the invention being to provide a pump for causing a circulation of uid through t 1e jacket of a gas engine and to so mount said pump and a tank from which it receives fluid, that one can move relatively to the other, whereby when the water in said tank has become frozen, the pump can be made to force water (which I may be poured upon he ice in the tank) through the water jacket of the engine, the return of said water to the tank acting to melt the ice therein,'and permit thcdcsccnt of the pump.

A further object is to provide means whereby the pump will be operated by the fly wheel of the engine.

With these and other objects in view, the

invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view illustrating my improvements and Fig. 1 is a view showing the application of my im )rovement to an engine.

1n the tank.

and Figs. .4 and 5 are views of modifications.

1 represents a water tank, to which warm water from the cooling jacket 20 of an ongine cylinder 21 is returned by pipe 2, and 3 A journal 4 projects outfrom the side of the engine frame adjacent to the periphery of the fly wheel, to receive a sleeve 5 on a bracket 6, and pivotally sup )ort the latter. 'lhis bracket 6 is provide-(i with rdwed tubes 7 and 8, in which a shaft f) is iii-muted, and a friction wheel 10 is arried on said shaft, be-

Fig, 2 is a simi ar view showing the 1 ump elevated above a frozen body of water Fig. 3 is a sectional view illus- 'trating the pump and easing construction,

' tween tubes 7 and 8, and engages the rim of the fly wheel I) and so as to be driven thereby. A coilcd spring 11 is located on journal 4 between the sleeve 5 and a nut 12 or the outer end of the journal, to maintain the friction wheel 1() in cngagcnu-nt wit h the fly win-cl.

The free end of tube 7 supports a cylindrical pump casing 13, in which a rotary or centrifugal pump propeller IT is located, and secured to shaft 5), to lorce the water through I a pipe 14 connecting the periphery of the pump casing with the engine.

The pump casing receives the water through a central inlet opening 18 in its bottom and by the centrilugal action of the propeller, discharges the water through I e 14 to the cooling jacket of the engine. The rapid revolution of propeller 17 has a tendency to create a vacuum at the upper central )ortion of casing 13, to compensate for which, water inlets it) are provided in the casing wall around the tube 7, to admit water and this water is forced out with the main 1 body of water admitted through 0 )cning 18. Without these inlets 1f), the propeller would suck air through tube 7 around shaft 9 and the pump would fail to work properly if at all.

During the normal operation of the apparutus the pump is submerged in the water and forces water through pipe 14 to the cooling jacket of the engine and the return of the water from the engine to the tank 1 is effected by the pipe 2. Should the water be frozen l in the tank, the pump can be rested on top of the ice, as shown in Fig. 2, and a sinal quantity of water supplied to the tank, the water thus poured upon the ice in the tank will be forced by the pump to the engine and returned in a heated condition to the tank to melt the ice, and as the ice melts the pump will move downwardly.

The tank is located lower than the engine cylinder, so as to drain the water back into the tank as soon as the engine stops, avoiding all possibility of freezing the water in the cooling jacket of the engine cylinder, and injuring the same. By having the pump 10- catcd directly in th water, check valves are nol required. 'lhcrcl'ore, the water will drain from the cylinder jacket. to the tank whcn engine stops and be forced to the jacket as soon as the engine is started.

lo the modification shown in Fig. 4, the

, pump is provided with a slotted bracket 15 for the accommodation of a suitable bolt. Nith this construction, the pump can be raised out of the water in the tank when not in operation, as shown in Fig. 4. Should the water in the tank freeze When the engine is not running, it is simply necessary (when the engine is to be started) to lower the pump and add sufficient water to the tank to start circulation.

With the construction shown in Fig. 5, the tank is hinged at 16, so that the tank can be lowered when the engine is not running. as shown by dotted lines. \Vhen the engine is started, the operator will raise the tank and if the latter contains ice, he will pour suiiicicnt water upon the ice to permit th pump to start circulation and the hot water returning from the water jacket of the engine through the pipe 2, will melt the ice in the tank.

Other changes might be made in the general form and arrangement of the parts described Without departing from my invention, and hence, I do not restrict myself to the precise details set forth but conside myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent is z- 1. in a device of the character described, the combination of a tank and a liquid forcing device having mountings ind epcndeut of each other, and one of said devices movable relatively to the other.

2. In a device of the character described, the combination with a tank and an engine of a pump to receive water from the tank driven by the fly whrcl of the engine and a movable mounting or support in: said pump.

3. In a device of the charar er described,- the combination with a tank and an engine, of a movable bracket, a shalt supported thereby, a friction wheel on the shaft to engage a wheel of an engine, a pump in the tank operated by the shaft, and a spring holding the friction wheel in engagement with the fly wheel.

t. In a device of the character described, the combination with an engine, and a tank located below the cooling jacket of the cylinder of the engine and into which said cooling jacket drains, of a pivotally supported pump in the tank and a pipe to convey water from the pump to the cooling jacket of the engine cylinder.

The combination of a tank and a pump, one movable relatively to the other, and engine means for connecting said pump wit?! the water jacket of the engine cylinder an means forconnecting said water jacket with the tank.

6. The combination with a tank and an engine, of a pump movable up and down and arranged to receive iluid from said tank, means for driving said pump, and means for con;

necting said. pump with the cooling devices of the engine.

7'. The combination with an engine having cooling devices, and a tank for supplying fluid for said cooling devices, of a pivotally supported pump constructed and adapted to take fluid from said tank and force the same to said cooling devices, and means fordriving said pump from a wheel of the engine.

8. The combination with an engine having cooling devices and a tank for su plying fluid to said cooling devices, of a va veless, centrifugal pump to force water from said. tank to the cooling devices and permit the fluid to drain back to the tank when the engine is at
